So very much buy now reasearch later on the 6s esc. But not terrible. So the 6s esc is for a 1/8th but has the same mounting points. However, its 4s backwards compatible, but has 2 battery connectors. Theyre in series and the thing its off has 2 battery trays. So 4s = 2x2s batteries, 6s=2x3s batteries. My truck has 1 battery tray. Not the end of the universe. Just take out the series link and re pin the battery connector so its just one. It'll run my existing 4s batteries fine. 6s, well, im still running the stock 2400kv motor so my estimate is 2 runs on 6s and ill be over the moon, but 3rd run the motor will be toast. Take your bets.
